Customer Questions & Answers

Is this coupling designed to slip onto pipe or will it wrap around the pipe without having to cut pipe to install?

Asked by: Gene
this is designed for PVC pipe repair (i.e. you desire to cut THROUGH a 4" pipe for some reason, like add a joint to run a new line or something, then you have to repair the cut. This is for drainage only (not anything with pressure). OK to bury this. Watch the video for helpful instruction. In the video is also something called a mission coupling which is a shielded coupling. Somethings you want some metal shielding. For buried water drainage or sewer lines, this is preferable as it gives you more "wiggle room" than the mission coupling.

Can it connect ABS piping?

For ABS outdoor drainage, is this compatible? If so, would it provide any useful flexibility? Thanks.

what type of clamp can be used to wrap around a sewage pipe with no cutting required?

cast iron or lead
Asked by: nia
stainless steel hose clamp s are best ! simply because they are rust proof so you get a permanent secure joint that is ok to bury.
